flink 1.7 HA production setup going down completely

[Manjusha Vuyyuru]

Hello,

I have a flink setup with two job managers coordinated by zookeeper.

I see the below exception and both jobmanagers are going down:

2019-05-07 08:29:13,346 INFO  org.apache.flink.runtime.jobmanager.ZooKeeperSubmittedJobGraphStore  - Released locks of job graph f8eb1b482d8ec8c1d3e94c4d0f79df77 from ZooKeeper.

Can someone please help me understand in detail on what is causing this exception. I can see zookeeper not able to retrieve job graph. What could be the reason for this?

This is second time that my setup is going down with this excepton, first time i cleared jobgraph folder in zookeeper and restarted, now again faced with same issue.

Since this is production setup this way of outage is not at all expected :(. Can someone help me how to give a permanent fix to this issue?

Thanks,

Which flink version are you using?
I had similar  issues with 1.5.x

Hi Manju,

could you share the full logs or at least the full stack trace of the exception with us? 

I suspect that after a failover Flink tries to restore the JobGraph from persistent storage (the directory which you have configured via `high-availability.storageDir`) but is not able to do so. One reason could be that the JobGraph file has been removed by a third party, for example. I think the cause of the FlinkException could shed light on it. Could you verify that the JobGraph file is still accessible?

Cheers,

Till

Hi Till,

Thanks for the response.

please see the attached log file.

HA config is : 

high-availability: zookeeper

high-availability.storageDir: hdfs://flink-hdfs:9000/flink/checkpoints

From the logs i can see block missing exceptions from hdfs, but i can see that the jobgraph is still present in hdfs.

pretty much explain what's happening. Flink cannot read all the blocks belonging to the submitted job graph file and fails due to this. This looks like a HDFS problem to me.

Hi Till,

Thanks for the response.

please see the attached log file.

HA config is : 

high-availability: zookeeper

high-availability.storageDir: hdfs://flink-hdfs:9000/flink/checkpoints

From the logs i can see block missing exceptions from hdfs, but i can see that the jobgraph is still present in hdfs.

Hi Manju,

could you share the full logs or at least the full stack trace of the exception with us? 

I suspect that after a failover Flink tries to restore the JobGraph from persistent storage (the directory which you have configured via `high-availability.storageDir`) but is not able to do so. One reason could be that the JobGraph file has been removed by a third party, for example. I think the cause of the FlinkException could shed light on it. Could you verify that the JobGraph file is still accessible?

Cheers,

Till

Hello,

I have a flink setup with two job managers coordinated by zookeeper.

I see the below exception and both jobmanagers are going down:

Can someone please help me understand in detail on what is causing this exception. I can see zookeeper not able to retrieve job graph. What could be the reason for this?

This is second time that my setup is going down with this excepton, first time i cleared jobgraph folder in zookeeper and restarted, now again faced with same issue.

Since this is production setup this way of outage is not at all expected :(. Can someone help me how to give a permanent fix to this issue?

Thanks,

Manju
